The pitcher and two other unidentified people were pronounced dead early Sunday after a Coast Guard patrol found a 33-foot boat overturned on a jetty about 3:30 a.m. local Miami time, according to Coast Guard Chief Nyxolyno Cangemi.

The Marlins, who were set to play the Atlanta Braves today, have canceled their game in light of the tragedy surrounding Fernández (pictured above, left, laughing with an umpire during a game last week).

Fernández was among the most exciting, talented young pitchers in all of Major League Baseball. A Cuban-born athlete, he was wildly popular in Miami and dazzled the league with his strikeout stuff, even overcoming major elbow surgery in 2014 to be the Marlins' ace starting pitcher.

This season, Fernández had struck out at least 11 batters in nine of his 29 starts, and had pitched to a phenomenal 2.86 earned run average with 253 total strikeouts up through his final start.

On Wednesday night, he made what turned out to be the last start of his career, and it was brilliant: in eight innings of work, he struck out 12 Washington Nationals batters in a 1-0 shutout victory.

Even more tragic, just five days ago, Fernández hinted that his girlfriend was pregnant (below):

On Friday, the 16-year-old Deakin shared the following image (below), a gorgeous portrait of the family with her late mother, Johannah Deakin, surrounded by all of her children:
